The recent emergence of a virus that typically sickens children in colder months has baffled U.S. pediatricians and put many infants in the hospital with troublesome coughs and breathing trouble. RSV, or respiratory syncytial virus, is a common cause of cold-like symptoms but can be serious for infants and the elderly. Cases dropped dramatically last year during COVID-19 restrictions but began cropping up as pandemic precautions eased. The U.S. Centers for Disease Control and Prevention issued a health advisory on June 10 about an increase in RSV cases across parts of the South. Cases have appeared in many other states.
